SUPALAND Toyota Prius Key Fob — 2004–2009 Silver-logo 3-Button, Ready-to-Program (MOZB31EG)

SUPALAND replacement key fob is a ready-to-program, three-button remote designed to fit Toyota Prius 2nd Gen (2004–2009) vehicles that use the silver-logo key style.

This SUPALAND remote substitutes the original P/N 2584A-B31EG / 89994-47061 (FCC ID: MOZB31EG) and ships with the electronic board and batteries preinstalled. It arrives as a blank key head and uncut physical key — you or a locksmith will need to cut and program it to match your vehicle. The listing is for the silver-logo style only, so confirm your existing key’s logo color and OEM identifiers before ordering to avoid compatibility issues.

How does this SUPALAND key fob match my Prius model?

This fob is made specifically for the second-generation Toyota Prius (2004–2009) that originally used the MOZB31EG transmitter. Compatibility depends on matching the FCC ID, part numbers, and button layout on your current remote. If those match, this unit is a physical and electrical equivalent ready for programming.

• Fits Prius model years 2004 through 2009 (2nd Gen)
• OEM references: P/N 2584A-B31EG, 89994-47061, FCC ID: MOZB31EG
• Three-button layout compatible with push-start systems
• Intended for silver-logo style keys only — check your original key

What comes in the box and what is preinstalled?

Each SUPALAND product includes one complete fob housing, the electronics board, and batteries already installed so you can proceed to programming without sourcing parts. The physical key blade is supplied blank and must be cut to your car’s ignition or valet key specification.

• 1 x SUPALAND three-button key fob housing
• Electronics board and battery included and tested
• Blank, uncut key blade for cutting to your vehicle
• No logo on the back of the replacement key—verify original logo color first

How do I program and get this key working with my Prius?

Some Toyota models support self-programming, but most push-start Prius units need at least one working key already present in the vehicle for successful self-program. If you do not have a functioning key, a qualified locksmith or dealership will be required to program and cut the new key.

• Self-programming possible only if you have one working key
• No onboard programming if you lack a working key — locksmith or dealer needed
• Professional cutting required to match your car’s ignition/valet key
• Contact SUPALAND or your dealer if you’re unsure about steps

What should I check before buying to avoid ordering the wrong fob?

Compare your current key’s FCC ID, part numbers, frequency and button appearance to the details for this SUPALAND replacement. Buying the wrong style or color (this listing is for silver-logo-style keys only) will result in a non-working key, and returns can be avoided by confirming OEM info first.

• Verify FCC ID: MOZB31EG and OEM part numbers 2584A-B31EG / 89994-47061
• Confirm your key has the same three-button layout and silver-logo styling
• Check frequency and transmitter appearance against your original fob
• If unsure, consult your dealership or contact SUPALAND support

Who is this for: This replacement SUPALAND key fob is aimed at Toyota Prius owners (2004–2009, 2nd Gen) who need a tested electronic remote housing with batteries included and are prepared to have the blank key cut and programmed. It’s ideal for DIYers who have an existing working key and for owners willing to use a locksmith or dealership to complete programming. Do not purchase if your original key uses a different logo color or different FCC/part numbers.
